Did you know your iPhone & iPad has multiple microphones with polarity patterns that are all available under the hood? This app accesses all of them. Select a mic and a polar pattern (mono only) or choose stereo recording in Settings. Monitoring starts at app launch, hit Record, add a marker if you hear something cool. Then play your recordings back, share them, and use them in your creations. Input gain is adjustable and you can push it to distort if you'd like. If you plug in wired headphones you can listen to your environment and what you're recording, there's plenty of extra monitoring gain there too if you need it. Bluetooth monitoring is also available with latency, but with noise cancelling enabled it works pretty well. All your recordings are stored on device and accessible in the Recordings page, where you can see any cue markers you've made, scrub through long recordings, rename the file, and share the file outside the app.
